Officials said Kellerman told police he had forgotten the gun was inside the bag.

Kellerman, who does not have a published phone number, could not be reached.

It was at least the second time this month that a passenger was charged with having a loaded gun at a checkpoint at Newark Liberty, after a 41-year-old Florida man was arrested with a loaded 9 mm handgun on Feb. 1.

That man also told authorities he had forgotten he had the gun in his bag.
